Autodesk Senior User Experience Designer interview questions

I was introduced to autodesk through an employee referral, I immediately got a call the next day from the HR and was asked to meet the Hiring Manager the same day. I was quite puzzled and managed to talk to the Manager about my past experience,portfolio,what i love to do and other stuff. He was quite Ok and said to me that they will send me a task and I need to send a solution within 5 days. I worked on the task and have sent the Wireframes,Visual Designs and Prototype of the Application. Later after 5 days the Hr got back to me and arranged a task review round with one of the Lead User experience designer. This review meeting was pidy cool and the lead was very sensible and chilled out..He appreciated my Visual designs though and said the Hr will get back to me. Then later i had a round with the Lead Product Manager and after that with the final HR where most of the questions were asked and was very cool though. There was a long waiting period to receive the offer letter and finally it took around 50 days of time frm the day i got the first call to receive an offer. Be Patient Guys...!
